Answer #1

Statistical significance refers to the claim that a result from data generated by testing or experimentation is likely to be attributable to a specific cause. The fixed level of Probability of Type 1 error is called level of significance. It is fixed before the data are collected.

The obesrved level of significance is minimum lecel of significance at which Null hypothesis(H0) is rejected for the given data

The Researcher simply reports the P-value for the data observed . If onwards to keep level of significance below P-value, Ho would be accepted. If he to keep level of significance above the P-value then Ho would be rejected

Consider the scenario: A research paper claims a meaningful contribution to the literature based on finding statistically significant relationships between predictor and response variables. In the footnotes, you see the following statement, “given this research was exploratory in nature, traditional levels of significance to reject the null hypotheses were relaxed to the .10 level.” Post...

Just because two or more values are different does not mean that they are different in a statistically significant manner. Researchers rely on the p values that are generated for each of their statistical tests to determine significance. If the p value is larger than the alpha, then they are not different in a statistically significant manner, and therefore the values are not considered different. In this journal activity, consider these concepts in terms of the differences between null and...
